Hey John,
Where I work all our online bays are PC, running mostly Windows 10. We don't have the option to do any kind of mix down to ProRes media.
If my source files happen to be ProRes I can read that on PC, and if there are no effects in a cuts only timeline, I have in the past exported "Same as Source" and gotten ProRes, but I haven't done it recently, to know if it works on current Media Composer versions. However in that scenario, the PC Media Composer cannot "create" any new media in ProRes. The option is not available in Media Creation settings.
What we do where I work is create an OP1a DNx175X file with audio, open that file on a Mac and do the ProRes export there. (Or do an uncompressed Video MixDown RGB with audio, in a sequence in a Bin).
Either way, That's how we get to ProRes. Always on a Mac, from MXF media. Mac Media Composer has the choice in Media Creation settings to use MXF or ProRes, and there is still the option to bring into Final Cut. I know there are some hoops our Avid Assists go through to prevent levels shifts, but I don't currently know what those are. (I'll ask and follow up tonight).

It has been my understanding for quite a while the best way to export ProRes out of avid is to do a video mixdown to prores and then export that same as source. This bypasses any involvement in the QT engine that is notorious for slight level/gamma shifts. I'm assuming this is still true.I'm helping out a post sup on a new show and they don't seem to have the ProRes codec on their systems. I'm not sure if they are PC or mac but sounds like PC to me. Wouldn't any mac have ProRes Codec available or is the the difference between reading ProRes and writing? I know without a QTPro license I could not export from QT 7Pro. All my macs have FCP7 installed so they got the QT 7Pro license. Is it possible that a new mac could not have the ability to write a ProRes file unless somthing like compressor etc... is installed. In such a situation be it PC or Mac would an internal video mixdown to ProRes exported same as source to a .mov create a proper ProRes QT? That's the impression I've gotten over the years. If this is correct then it appears Avid can write a prores file internally or render to prores without the need for the QT codecs. Am I understanding this correctly?John Moore Barking Trout Productions Studio City, CA bigfish@pacbell.net
